Hi I was wondering what would be a good amp for blues/jazz/classic rock music. I would hopefully have it go with the fender jazz that I want

ehh probably like $600 I dont have the money now (all I have is 1300 which is reserved for bass) but this is something for me to look into in the future.
Check out the Acoustic B200 (the half stack comes with either a 1x15 or 4x10 with the B200H head), the Ashdown MAG300 and a cab of your choice, or a Peavey Tour 450 and a cab.

If you're willing to go used, you could look for an older Peavey, or maybe even a Carvin head. Definitely look used for a cab, used cab's are pretty cheap and you can save a good chunk of money to put towards the head.
